3. For the 4-5 component, when hyperfine optical pumping cannot exist, the narrow resonance remains an increased absorption in a more extended intensity range, but the transition between the present linear behavior and the nonlinear behavior, due to Zeeman optical pumping, appears as a change in the line shape.

8. The need to use a time-dependent theory in cw spectroscopy has been recognized in the context of optical pumping, by various groups; see, e.g., J. E. Bjorkholm, P. F. Liao, and A. Wojkaun, Phys. Rev. A 26, 2643 (1982).
9. Note that the optimal case (Formula presented) is the one considered in Ref. 2.
10. In our case, the two cell windows are not perfectly parallel. Taking into account an effective cell length increases the washing out of the (Formula presented) contribution.

12. Note that, in the principle, and due to the narrower structure of the (Formula presented) term (see Fig. 22), (Formula presented) may remain comparable with (Formula presented) as long as (Formula presented) but that any interferential averaging washes out the (Formula presented) contribution.
